best time to change your oil is right after a ride. not when the engine is
cool.

david ervin says:

use 4 stroke oil dude dont put car oil in a bike a little bit to top off is
okay. but you want the best oil possible its the life blood of your engine

keepitrunning says:

It’s sort of right about the oil, I used a motor oil in most of my bikes
though, which are early 80’s Honda’s in the main. Castrol GTX semi
synthetic and never had a problem. I remember when they were new ( well the
one I had myself since 1981) that’s what used to used in the workshop
anyway at the Hinda dealers where I worked and still work. Not nowadays,
granted, but then mostly they’re working on newer bikes these days so use a
specific ( usually semi synth) oil, For anything up to the mid nineties
though I believe what i use to be perfectly acceptable, for the sort of
mileage per year my bikes split between them anyway. I’d be lucky if I got
a thousand miles in on some of them, which I used in the good weather and
the oil comes out in good grade still. Only my 250’s get oil changes
outside that time as I like to do them every 1000 miles or so anyway.
I’m thinking about getting some else non Honda and old, like a
GS400,XS360/400, Z400 sometime in the next year or three, depending on
other circumstances and how much work my other bikes need. I do like to
have something to work on when I don’t feel like riding. Or A CJ360 or
CB400T1 maybe. It’ll depend on what turns up.

EL ACEITE? ¿ COMO SE CAMBIA EL ACEITE A UNA SUZUKI 550CC 1980, Gracias

david ervin says:

wouldof been nice to specifiy some things. the drain bolt takes a 22
milimeter and the oil filter is a kn-133. just so people know

keepitrunning says:

I see you found out different with the oil, good show. I would advise
anyone attempting even this ‘simple’ job to invest in a workshop manual,
also as old piece of carpet or cardboard to lie on and some newspaper or
rag for putting the parts on. It made my skin crawl to see you putting
parts on the ground.

Kathleen Zuchowski says:

Thank you for sharing!! I’m going to change the oil/filter on my 1982
GS450A tomorrow! 

alekzandru221 says:

you remind me of mac miller. Great info.

ohnoy2k says:

Thanks for posting. I’m in the process of resurrecting an ’80 450l.
Accidentally left the petcock open and fuel drained to my case

continueliving clan says:

Thanks for making this video!

Matthew Hurley says:

I can’t be certain, this was my first bike 😉 But from what I’ve seen of
the other 1980 and 1981 GS models, they’re all VERY similar. I think they
made some more significant changes with the ’88 or ’89, but with your ’83
it should go a lot like this. Also, this was the first time I’d changed the
oil on ANY bike, so you can see that it was pretty easy to figure out as I
went 😉

ohnoy2k says:

thanks alot man

Technostructural says:

Thanks a lot for posting this video. It helped me through the same thing a
few days ago. One footnote that I’ll add to this (if it’s ok), is to be
careful not to over torque those three acorn nuts. The bolt and nut on mine
stripped really easily, and it was not easy finding a replacement. I ended
up just machining my own bolt and using a nylon lock nut instead of the
acorn. A bike of this vintage will usually see stripped bolts without much
effort. That plate doesn’t need much force to seal.

hurleyman77 says:

yeah, I rode mine to Austin and back twice (4hrs one way). The first time,
the right muffler tip fell off and I rode all the way back on 1.5 pipes.
The second time, one of the carb boots to the head came loose and it
started sucking too much air, so I rode all the way back on one cylinder.
Then on the way back from San Antonio, I had to zip-tie a car bulb from
WMart to the front cuz all the parts places were closed when my headlight
burned out. Yeah, tough little booger 😉

davebo48 says:

thanks! good video. I just bought a 1979 gs850 and i knew were the oil
filter was , but it looked like alot deffrent setup than my honda cb750
bobber. you helped take out some of the mystery . setup looks about the
same. thanks!

GuitarDisciple1000 says:

Is the procedure the same or the bigger versions? I have an ’83 GS850GL.

hurleyman77 says:

@SuperLastboyscout I’ve gotten mine up over 100 mph 😉

ohnoy2k says:

Oh also quick question. What size tire are you running in the rear? Looks
like the previous owner of mine put a 130/90 on there which is rubbing the
chain. 120/80?

hurleyman77 says:

Actually, I’m not sure. I know they’re not stock, cuz they were rubbing the
chain guard (not the chain, tho). I’ll take a look and get back to you.

hurleyman77 says:

Lol! Glad I could help. I had to take mine apart before I figured out which
setting did what 😉

hurleyman77 says:

They’re 120/90-16

Michael Realista says:

How do you open the crank case?

Zachary Cotroneo says:

Thank you so much for this video. I’m off to go pick up my first bike, so
excited I’m almost crying, but it’s a 1984 Suzuki GR650. I know a little
more Motorcycle than the passer-by, but I ain’t no pro so… this video
really helped me, thanks!

gothechasers says:

Awesome! Thanks

ohnoy2k says:

Oh! Well that’s good to know. I guess I should have done more research on
that on position. Thanks for the tip

Matthew Hurley says:

If you’re asking about what I’m doing at :56, I’m just opening the screw-on
lid where you add the oil. I’ll add a note to make that more clear, thanks.

bcrem67 says:

Just bought an ’81 – muchas gracias, very helpful.

Mitchell Sikkema says:

u look like the bad guy off of act of valor haha

SuperLastboyscout says:

I rode the wind on a GS450L amazing I’m alive.

hurleyman77 says:

Sry for the long reply. I’m not sure. You’ll notice the UPC on the socket I
use for the drain plug. I had to buy that one special cuz it’s a little
bigger than what comes in your typical socket set. IIRC, it was a 7/8 or
19mm or something. The acorn nuts I’m also not sure about, but they were
much smaller, something like a 10-11mm. Neither size was “weird” so you
should have everything you need if you have a set of metric sockets and a
set of SAE sockets. You could also use wrenches, of course.

Mike hirsch says:

good video for people . I also ride Suzuki a bandit 99 with 70k miles and
my oil of choice is Castrol 20/50 because of the heat in Alabama . also
going to get a gs 850 today sweet ride. one other note suzukis are tougth
so ride it like u stole it lol

Ss010101 says:

Looks to be the same setup as my ’82 GS550L. That was helpful. Thanks!

Alex Kremer says:

Hi..what size socket are you using for both the oil plug and acorn nuts?

ilshockll says:

great video. thanks a lot. i’m working on a 1981 gs450 ex. its in pretty
rough shape but i think it has potential.

hurleyman77 says:

Cool! I’ve been riding mine for almost 2 years and I love it. Too bad about
the petcock, tho. IDK if u know already, but “ON” uses a vacuum valve
(opened by engine vacuum, closed when the engine stops), so u should be
able to leave the petcock there all the time, whether you’re running or
not. “PRI” bypasses that vacuum valve and will drain it ;-), and “RES” is a
reserve that is also vacuum controlled. …unless yours is different 😉
